The article presents the research results of changing the quality characteristics of information search in time illustrated by the example of five global search systems. The implementation of semantic measure and partial semantic measure of definition search query results was estimated to display that the automated search systems are in a position to output the pertinent documents at simple select query.To analyze the stability over time the results of information retrieval, in the use of quantitative indicators for implementation of the sequence of normalized conditional queries. Defined methodology for conducting trials to capture the dynamics of semantic query results to measure the automated retrieval information systems.We used the quantitative characteristics specifying the conditional standard query sequence implementation to analyze the stability of retrieval results in time. It was defined the methodology for conducting trials to capture the dynamics of semantic query results to measure the automated retrieval information systems.The article presents dynamics of completeness semantic relations and semantic measures of the SERPs information retrieval systems Yandex, Rambler, Nigma, Qip, and Mail.ru. Based on the realizations of random trajectories semantic dependency measures and partial measures, mean values are calculated for the observation period. Analysis of variance values of the partial measures as a function of weight showed that among the surveyed search engines, Mail.ru has to some extent the possibility of pertinence search.

The concepts of semantic measure and partial semantic measure are introduced in this paper for the first time. The results of such characteristics computing on the example of ten popular search systems are obtained. The proposed approach to evaluate the quality of information search systems has allowed to generate a criterion for testing the ability of pertinent documents issue.

The article presents a an information search model based on using descriptors which enables to consider the boundaries of sets as being inexplicit. The queries concept membership functions are defined. The approach considered by the use of semantic relations enables to form boundary sets of both documents corresponding to the descriptors and documents not quite corresponding to a query, but which may be enabled in the future.
